Description

Technical Field

[0001] This utility model relates to the field of new energy technology, specifically to a cable control and protection device with touch-sensitive current switching. Background Technology

[0002] With the increasing popularity of new energy vehicles, charging safety and convenience have become key aspects of ensuring the user experience of new energy vehicles. In the charging scenarios of end users, the convenient home charging gun with on-cable control and protection device has become one of the commonly used charging devices due to its flexibility and practicality. The on-cable control and protection device has the feature of replaceable charging plugs. This design is intended to adapt to different specifications of charging interfaces and meet diverse charging needs. However, different specifications of charging plugs have different rated currents, which requires the on-cable control and protection device to adjust the current according to the plug used to ensure the safety and stability of the charging process.

[0003] Existing cable-mounted control and protection devices suffer from functional deficiencies or operational inconveniences in current switching. They can only charge with a fixed current value and cannot flexibly adjust according to the rated current of different plugs. This may not only lead to low charging efficiency but also damage the vehicle battery or charging equipment due to current mismatch. In addition, although some devices theoretically have current switching capabilities, they must rely on external equipment to realize the current switching operation, which undoubtedly increases the complexity and cost of use and reduces the user experience and charging convenience. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a touch-sensitive on-cable control and protection device for switching current. This solves the problems of functional deficiencies or inconvenient operation in current switching, which can only charge at a fixed current value and cannot be flexibly adjusted according to the rated current of different plugs. This may not only lead to low charging efficiency, but may also damage the vehicle battery or charging equipment due to current mismatch. In addition, although some devices theoretically have the ability to switch current, they must rely on external equipment to realize the current switching operation, which undoubtedly increases the complexity and cost of use, and reduces the user experience and charging convenience.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a touch-sensitive cable control and protection device for switching current, comprising an upper cover and a lower cover. The upper cover is snapped onto the top of the lower cover. A label is affixed to the top of the upper cover. A lighting area 1 is formed on one side of the label. Multiple cavities are formed at the bottom of the upper cover, corresponding to the bottom side of the lighting area 1. A lighting area 2 is formed on the other side of the label. A label is affixed to the top of the upper cover. A light guide plate is snapped onto the bottom of the upper cover. A signal PCBA circuit board is provided on the bottom side of the light guide plate. A current indicator light is fixedly connected to one side of the top of the signal PCBA circuit board. A power indicator light is fixedly connected to the other side of the top of the signal PCBA circuit board. Multiple current indicator lights are provided. The multiple current indicator lights are connected to multiple cavities in the lighting area 1. The power indicator light is connected to the lighting area 2. A spring is elastically connected to the top of the signal PCBA circuit board, and the spring is located on the bottom side of the lighting area 1.

[0006] Preferably, a main PCBA circuit board is fixedly connected inside the lower cover, and the signal PCBA circuit board and the main PCBA circuit board are electrically connected. In this invention, the signal PCBA circuit board and the main PCBA circuit board can work normally together.

[0007] Preferably, mounting holes are provided on the surface of the signal PCBA circuit board and the bottom of the top cover. Screws are threaded into the mounting holes. The signal PCBA circuit board is fixedly mounted to the bottom of the top cover by the screws. In this invention, the assembly of the signal PCBA circuit board and the top cover is completed by placing the signal PCBA circuit board at the bottom of the top cover and then fixing the signal PCBA circuit board and the top cover together by screws and mounting holes.

[0008] Preferably, the top of the spring abuts against the bottom of the top cover. In this invention, when the entire system assembly is assembled, the spring is in a compressed state. When the current is switched by touch, the human finger will generate an induced current in the spring through the label. The spring transmits this signal to the signal PCBA circuit board, which transmits the signal to the main PCBA circuit board through a cable. After receiving the signal, the main PCBA circuit board performs current switching.

[0009] Preferably, the label is made of plastic, and the positions of the corresponding light-up area one and light-up area two on the label are designed to be light-transmitting. In this invention, processing raw materials can be saved, and the light-transmitting design allows each indicator light to be seen through the label.

[0010] Preferably, the light guide plate is supported by a transparent material, and the interior of the light guide plate adopts an anti-scattering structure design. In this invention, the use of a transparent light guide plate can transmit the light source to the label, and through the label to the human eye, so that people can see the light is on. The anti-scattering structure design can prevent two stray lights from entering the lit area.

[0011] (III) Beneficial Effects This invention provides a cable-mounted control and protection device with touch-sensitive current switching. It has the following advantages: (i) This touch-sensitive cable-mounted control and protection device, when touched by a human hand, generates an induced current in a spring. The spring transmits this signal to the signal PCBA circuit board, which then transmits the signal to the main PCBA circuit board via a cable. Upon receiving the signal, the main PCBA circuit board switches the current. Thus, by touching buttons for different current values, the device can be switched to different currents. Therefore, the current of the device can be switched by touching the touch of a finger, and after switching, the corresponding current indicator light can be lit separately to remind the end user of the actual switched current value. This allows end users to switch the current by matching different power plugs when no external devices are needed, improving the convenience and flexibility of the device during use. Furthermore, the product has an exquisite appearance and reliable performance, enhancing the user experience.

[0012] (ii) The on-cable control and protection device with touchable current switching, through the setting of light-transmitting labels and transparent light guide plates, can transmit the light source of each indicator light through and to the human eye, so that people can intuitively observe the switching current value. Furthermore, the light-emitting structure on the light guide plate can prevent light from crossing between each indicator light, making each indicator light clearer. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figure 1-4 This utility model provides a technical solution: a touch-sensitive cable control and protection device for switching current, the structure of which includes an upper cover 1 and a lower cover 2. The upper cover 1 is snapped onto the top of the lower cover 2. A label 5 is affixed to the top of the upper cover 1. A lighting area 3 is formed on one side of the surface of the label 5. Multiple cavities are formed at the bottom of the upper cover 1, corresponding to the bottom side of the lighting area 3. A lighting area 4 is formed on the other side of the surface of the label 5. A light guide plate 6 is snapped onto the bottom of the upper cover 1. A signal PCBA circuit board 7 is set on the bottom side of the light guide plate 6. A current indicator light 8 is fixedly connected to one side of the top of the signal PCBA circuit board 7. A power indicator light 9 is fixedly connected to the other side of the top of the signal PCBA circuit board 7. Multiple current indicator lights 8 are provided. Multiple current indicator lights 8 are connected to multiple cavities in the lighting area 3. Power indicator lights 9 are connected to the lighting area 4. A spring 10 is elastically connected to the top of the signal PCBA circuit board 7. The spring 10 is located on the bottom side of the lighting area 3.

[0017] The lower cover 2 has a main PCBA circuit board 11 fixedly connected inside. The signal PCBA circuit board 7 and the main PCBA circuit board 11 are electrically connected, which enables the signal PCBA circuit board 7 and the main PCBA circuit board 11 to work normally.

[0018] The signal PCBA circuit board 7 and the bottom of the top cover 1 are provided with mounting holes 12. Screws 13 are threaded into the mounting holes 12. The signal PCBA circuit board 7 is fixedly mounted to the bottom of the top cover 1 by the screws 13. Specifically, by placing the signal PCBA circuit board 7 at the bottom of the top cover 1, and then fixing the signal PCBA circuit board 7 and the top cover 1 by the screws 13 and the mounting holes 12, the assembly of the signal PCBA circuit board 7 and the top cover 1 is completed.

[0019] The top of the spring 10 abuts against the bottom of the top cover 1. Specifically, when the entire system assembly is assembled, the spring 10 is in a compressed state. When the touch switches the current, the human finger will generate an induced current to the spring 10 through the label 5. The spring 10 transmits this signal to the signal PCBA circuit board 7. The signal PCBA circuit board 7 transmits the signal to the main PCBA circuit board 11 through the cable. After receiving the signal, the main PCBA circuit board 11 performs current switching.

[0020] The label 5 is made of plastic, and the corresponding light-up areas 3 and 4 on the label 5 are designed to be light-transmitting. Specifically, this saves on raw materials and allows the indicator lights to be seen through the label 5.

[0021] The light guide plate 6 is supported by transparent material, and the interior of the light guide plate 6 adopts an anti-scattering structure design. Specifically, the transparent light guide plate 6 can transmit the light source to the label 5 and then to the human eye through the label 5, so that people can see the light is on. The anti-scattering structure design can prevent light from scattering in the lit area 4.

[0022] Working principle: When assembling the device, firstly, label 5 is pasted on the top of the upper cover 1, and the first lighting area 3 and the second lighting area 4 are respectively positioned on the top side of the current indicator 8 and the power indicator 9. Then, the light guide plate 6 is installed into the bottom of the upper cover 1, and the signal PCBA circuit board 7 is assembled into the bottom of the upper cover 1 through screws 13 and mounting holes 12. The signal PCBA circuit board 7 is connected to the main PCBA circuit board 11 through a cable. Then, the upper cover 1 assembly and the lower cover 2 assembly are fixedly installed, thus completing the assembly. In use, after the entire system assembly is assembled, spring 10 is in a compressed state. When a person touches the switch current, their finger will generate an induced current through label 5 to spring 10. Spring 10 transmits this signal to signal PCBA circuit board 7. Signal PCBA circuit board 7 transmits the signal to main PCBA circuit board 11 through a cable. After receiving the signal, main PCBA circuit board 11 performs current switching. There are switching current lighting points in lighting area 1 3. Each current point has an independent current indicator light 8 on signal PCBA circuit board 7. When switching, the corresponding current indicator light 8 in lighting area 1 3 lights up to correspond to the current value at the upper end. When the device is charging, lighting area 2 4 lights up, that is, the power indicator light 9 lights up to remind people of the charging status of the device.
